VAPOR SAD-IRO N.

SPECIFICATION forming part of Letters Patent No. 430,164, dated June 17,1890. Application filed September 20, 1889- Serial No. 324,531. (Nomodel.)

.Toall whom it may concern:

Be it known that we, IVILLIAM P. YOUNG and CHARLES D. MIDDLEKAUFF, ofthe city of San Francisco, San Francisco county, California, haveinvented certain new and useful Improvements in Vapor Sad-Irons, ofwhich the following is a full, clear, and exact description, referencebeing had to the accompanying drawings, forming a part hereof.

Our invention relates to an improved vapor sad-iron and it consistsinacertain novel construction and combination of parts, fully describedhereinafter in connection with the drawings and claimed.

In the drawings, Figure 1 is a side view of a sad-iron embodying ourinvention. Fig. 2 is a'rear elevation of the same. Fig. 3 is a verticallongitudinal section taken on line mic of Fig. 2, and Fig. 4 is a detailperspective view of the burner and connecting-pipe with thedeflecting-flanges secured thereto.

A represents the improved iron, which is provided with a hollow base Bof steel or other suitable material, having a bottom D, a-top C, and thesides and back E. The rear end of the base is provided with an openingX, and the sides are provided near the front with perforationsocforventilation, and F represents a dovetailed slide which fits in adovetailed slot f in the side of the base and carries a block F, asshown in Fig. 2. This slide F F is removable to enable the swingingburner, which is hereinafter described, to be swung out when it is to belighted.

The handle G is hollow, being provided with a boreg to contain gasoline,which forms the fuel for the burner, said hollow handle being supportedat one end by a solid standard U and at the other end by a tubularstandard I. The solid standard is formed integral with the handle andthe top of the base, and the tubular standard is screwed into a threadedopening in the bottom of the handle and passes at its lower end througha registering opening in the top of the base. The enlarged shoulder N onthe lower end of the tubular standard is received in a recess a in theunder side of the top of the base and is engaged by a hood-nut M, and aswivel-tube P fits at its upper end in the enlarged lower end of thebore of the tubular standard, and

is provided with a small tubular extension 19 to fit in the bore of thesaid standard. The swivel-tubeis further provided with an annular collarp, which fits in a corresponding recess or enlargement in the lower endof the standard I, and is held in place therein by the hood-nut M.

On the lower threaded end of the swiveltube is screwed one arm of theelbow-sleeve O, and into the other arm of said sleeve is fitted one endof the filter-tube Q, which is inclined upward toward its free end, towhich the burner R is connected by means of the elbow-sleeve R. Theburner-tube is closed at its lower end by the plug 8, and is perforatedabove said plug, as seen at s, and to the upper end of the burner areaflixed the downwardly-curved deflecting-flanges S, which de-. fiect theheat from the burners against the bottom of the base, therebyconcentrating the heat. The upper or forward end of the filter-tube andthe elbow-sleeve are filled with a wire-gauze filter r, and the otherend of said tube is filled with the asbestos filter 0*, whereby the fuelis filtered before reaching the burner.

As will be understood, the swivel-tube enables the burner to be swungout through the opening in the side of the base when it is to belighted. A finger-slot f is formed in the slide F, to enable it to bedrawn out.

J represents a sleeve, which is fitted on the tubular standard I andcarries the valvecasings jj, having threaded bores, in which fit thethreaded stems Z Z of the valves L L, said valves being adapted to closethe bore a of the tubular standard. Cap-nuts K K are screwed on the endsof said valve-casings around the valve-stems and are provided with thefilling or packing d.

H represents a vapor-duct, which extends from the top of thegasoline-reservoir or handle to a point in the tubular standard betweenthe valves L L, and communicates therewith through the perforation h,which is shown in Fig. 3, whereby the vapor which arises from thegasoline is conducted to the tubular standard and thence to the burner.

One end of the handle or reservoir is provided with an opening, in whichfits a stopper T, which, when removed, enables the interior of thehandle or reservoir to be cleaned and relieved of any sediment which mayaccumulate, and in a similar opening 0, near the opposite end of thehandle or reservoir,is fitted a stopper a, which bears on a packing Z),this opening being provided to enable the reservoir to be filled.

Over the top of the base is arranged a thin metallic shield V of copperor other suitable material, having its edges curved downwardly to formflanges t, which bear on the top of the base, and between this shieldand the top of the base is introduced an asbestus filling W. The shieldis provided with collars e, which surround the standards U I andstrengthen the same.

The operation of our invention is as follows: The valves L L beingopened, the gasoline fiows through the tubular standard and thefilter-tube to the burner, where it is ignited, said burner having beenpreviously swung outward through the opening in the side of the base, asbefore described. After the combustion has continued a suflicient lengthof time the heat is conducted through the standards U I to thereservoir, and as the latter becomes heated the gasoline is vaporized,the vapor being conducted off through the duct H to the tubularstandard. The upper valve L is now closed,thereby cutting off the fiowof gasoline and permitting the vapor alone to pass to the burner. Theshield on the top of the base protects the hand of the operator from thedirect radiant heat, but does not prevent the heat from being conductedto the reservoir or handle through the standards, and as gasoline isvaporized at a comparatively low temperature said handle or reservoirwill be hot enough to vaporize the gasoline without being 'too hot to becomfortably held by the operator. To extinguish the flame, the lowervalve L is closed.

Having thus described our invention, we claim- 1. In a vapor sad-iron,the combination,

with the hollow base and the hollow handle or reservoir, of the hollowstandard I, having its bore enlarged at its lower end,the swiveltubefitting in said enlarged bore and provided with a collar 19, thehood-nut fitting on the lower end of said standard, and the burnerconnected to said swivel-tube, substantially as specified.

2. A vapor sad-iron having a hollow base, a hollow handle connected atone end to the base by a solid standard, a tubular standard having aburner connected to its lower end and communicating at its upper endwith the interior of the handle, said standard being provided withvalves, and a vapor-duct communicating with the interior of the handle,and with the tubular standard between said valves, substantially asspecified.

3. In a vapor sad-iron, the combination, with the hollowreservoir-handle, of the tubular standard connecting the base andhandle, said standard being provided with an upper and a lower valve,and a vapor-duct communicating with the upper portion of the handle,and'with the tubular standard between the valves, and a supply-tubeswiveled in the lower end of the tubular standard and provided at itsfree end with a downwardly-projecting burner, substantially as shown anddescribed.

4. In a sad-iron, the combination, with a hollow base having an openingin the side thereof and a suitable slide for closing the same, of areservoir-handle, a tubular standard connecting the handle and base, anda downwardly projected burner swiveled in the lower end of the tubularstandard and adapted to be swung without when igniting, substantially asshown and described.

In testimony whereof we aflix our signatures in presence of twowitnesses.
